We have a gaming group on Discord going that runs a variety of systems, if you'd like to join. We're pretty friendly and are more than willing to teach new people how to play or how to DM. If you're interested, hit me up and I'll send you the Discord invite.

I once rolled almost max damage on a Dead Shot attack with Smite Tyrant using a +5 Thundering Shocking Burst Distance Railgun, with technic training in rail guns.
That was an almost max roll on 48d10+56 (Dex bonus from Technic Training x4) + 20 (4x the +5) + 3d8 (Sonic) + 3d10+1d6 (Elec). Ignoring all Hardness and DR. In a 4000-foot line that pierced everything. Almost 556b/p+24sonic+36elec damage (616 total damage). Nothing hit survived, but if they had, they would have also had to have made a save to avoid going permanently deaf.
I think that gunslinger may have been one of my favorite pathfinder characters, to date. Probably why I loved Iron Gods so much.
